Police have not commented on what footage was recorded on the camcorder Plitt was holding when he was killed, however the Bravo star had shot a number of workout videos on train tracks in the past.

Before becoming an actor, a workout guru and a fitness model, Plitt served as a U.S. Army Ranger for five years after graduating from West Point in 2000.

Plitt recently starred in an episode of Bravo's new reality series Friends to Lovers, which premiered Jan. 12. His episode was scheduled to air in the coming weeks.

Bravo producer Andy Cohen tweeted a message of condolence Sunday morning, writing: "We couldn't take our eyes off Greg Plitt after we cast him on Work Out -- was as nice as he was beautiful. Seemed invincible, like Superman."
